Sarah Jessica Parker suffered wardrobe malfunction when attending the 2013 MET Ball on Monday, May 6 at the Metropolitan Museum of Arts. The 48-year-old actress accidentally flashed her black lacy knickers when pulling up her Giles Deacon ballgown to highlight her legs in a pair of thigh-high Louis Vuitton plaid boots.

To comply with this year's theme, Punk: Chaos To Couture, Parker donned a gold Mohawk-shaped headpiece by Philip Treacy, which caught Jennifer Lawrence's attention. Lawrence and Parker then laughed when the "Silver Linings Playbook" actress touched the headdress.

Parker completed her look with a large diamond necklace and matching earrings. She looked natural as she wore her black-rimmed eyes and went with nude-colored lipstick.

Also attending the event was Madonna. The pop singer went all-out in a Givenchy blazer with ripped fishnet, a studded collar, waist belt and a black fringed bob haircut. Meanwhile, Miley Cyrus stepped out in a fishnet dress with her hair shaped in spikes.
